Varignon's theorem, Pierre de Varignon, quadrilateral, bisector, bimedian, parallelogram

 

A Short Note:

The situation is similar to that of a triangle:  There the medians divide one another in the ratio 2:1. In the case of a quadrilateral the bimedians divide one another in the ratio 1:1. It is evident that through these bisections you get a parallelogram. (But this is not a proof!)

 

This theorem is named after Pierre de Varignon (1654-1722). More information? [here]

 

Proofs and further relationships you can find [here], [here] or [here].
